代碼貼出,分享給大家:
後台test.aspx.cs代碼:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Text;
public partial class test : System.Web.UI.Page
...{
protected string strJS;//這個變數是要傳遞到前台JS代碼中的,變數聲明的位置一定要在Page類首部,且必須聲明為受保護的:protected
protected void Page_Load(object sender, EventArgs e)
...{
}
//點擊按鈕事件,在前台動態產生一段JS代碼
protected void Button1_Click(object sender, EventArgs e)
...{
string[] str =...{"aaa","bbb","ccc"};
StringBuilder sb = new StringBuilder();
sb.Append("name='"+str[0]+"' ");
sb.Append("sex='"+str[1]+"' ");
sb.Append("age='"+str[2]+"' ");
strJS = sb.ToString();//給strJS賦值
}
}
前台test.aspx代碼:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>無標題頁</title>
<script>
var name;
var sex;
var age;//這三個變數和後台傳過來的strJS中的變數一致的
<%=strJS %>//這句是關鍵,相當於response.write(strJS),就是動態產生了一段JS代碼,在你點擊了按鈕後,就會動態產生這段代碼,這段JS代碼是一段指派陳述式,你可以在點擊了按鈕後查看網頁的源檔案
function print()
...{
alert(name+' '+sex+' '+age);
}
</script>
</head>
<body onload="print()">
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></div>
</form>
</body>
</html>
